The entire electrical system is taken from the 1986 Toyota Corolla GT-S donor.
The headlight loom was unwrapped and some wires relocated. The engine loom is untouched. The dash loom has had all unnecessary wiring removed, and has been shortened to fit the Locost dash.
The intent is to make this vehicle easily serviceable by any Toyota technician.
Some problems encountered were mainly missing wires.
- Don’t forget to ground the engine to the chassis
- When removing the pop-up headlight circuitry, be sure to connect power to the switch (red/white wire to and from the retracter relay)
- There are only two wires the same colour at the engine/firewall coupling (fat, squarish plug) – black/white. They are for Cruise Control and Tachometer. Do not mix them up.
- The Neutral Safety Switch is a Normally closed switch. It needs to be activated when the clutch pedal is depressed, not released. Bugger.
15 feet of shrink wrap, 3 rolls of electrical tape, and only 6 mistakes!
If I were to do it all over again, I would have pulled ALL the wire out, and wired each circuit individually. It would have made for a MUCH simpler, MUCH tidier harness. FSM convenience be damned. Making changes after the fact is a whole new level of frustration.
